The length y of a rectangle is four less than three times the width x. The perimeter of the rectangle is 16 cm.
Anettt [7]

Answer:

y = 1 cm

x = 7 cm

Step-by-step explanation:

x = 3y + 4

perimeter = 2 * ( y + x ) = 16

x + y = 8 by using x = 3y + 4

y + 3y + 4 = 8

4y = 4

y = 1

1 + x = 8

x = 7

y = 1 cm

x = 7 cm

Suppose that a​ person's peak blood alcohol level is 0.07 ​(grams per 100​ mL) and that this level decreases by 40​% each hour.
Natalija [7]

Answer:

Step-by-step explanation:

Considering a person peak blood is 0.07

It decrease by 4% every hour

a) Using exponential function

f(x) = Ca^x

where,

a = 1 + r

r = -0.40%

Here,

C = 0.07,

a = 1 - 0.04 = 0.06

f(x)=0.07(0.6)^x

<h3>Therefore, hourly decay factor is 0.6</h3>

b)

Here the hourly decay factor is 0.6

B(x)=ca^x\\\\0.07(0.6)^x

c) Evaluate

B(2)=0.07\times (0.6)^2\\\\0.07(0.36)\\\\= 0.0252g

0.0252g or 100mL

<h3>Thus, after 2 hours the blood is 0.0252g or 100mL</h3>

76/5 x 8/18

76x8=608

5x18=90

608/90

Simplify

608/2=304

90/2=45

304/45

6 and 34/45 meat loaves
